To review the complications encountered in our facility and in previously published studies of transvaginal (TV) natural orifice transluminal endoscopic surgery (NOTES) to date. ⋯ As techniques in TV surgery are adopted, inevitably, complications may occur due to the inherent learning curve. Laparoscopic instruments, although adaptable to TV approaches, have yet to be optimized. A high index of suspicion is necessary to identify complications and optimize outcomes for patients.

Comparative Study Clinical Trial
Effect of gastric bypass versus diet on cardiovascular risk factors.
To assess the effect of Roux-en-Y gastric bypass (RYGB) on high-density lipoprotein cholesterol (HDL-C) concentration and its apolipoprotein A4 (ApoA4) content at 1 year after bariatric surgery in comparison with a hypocaloric diet. Secondary aim was to measure total cholesterol and triglycerides levels and insulin sensitivity after interventions. ⋯ Our study shows that HDL-C and ApoA4 significantly increase after gastric bypass and that this increase is associated with a net improvement in hepatic insulin sensitivity. Furthermore, we speculate that ApoA4, which induces satiety in animals, can eventually play a role on the appetite reduction after RYGB because there is a strict and inverse relationship between weight and ApoA4 changes.
